The object of my invention is to producea gang filing device adapted for Vfiling several parallel-openings at the sametime and oper-` ated by power means.

Another Objectis to produce a special gang filing device which is particularly adapted for removing the rough edges within-the wiring slots of electric starterand generator arma.- ture cores, where these slots are paralleland arranged in a circle about .the outer circumference of the armature. i

A further object is to produce a gang ling device actuated by a sli'dable filing head and that is constructed with adjustable parallel files, all capable of radial adjustment against spring supports for forming contact with the work. l l

Another object is to produce a power gang tiling device so designed that all of the iilesf will loperate alternately sidewiseand edgewise i with each movement of the operating crank.

rlhese several objects are attained inthe preferred form by the construction and arrangement of parts more fully hereinafter set forth. Y i .l Y

v Vlngeneralmy device comprises abase'casti ing having a circular gang filing head'slidably mounted on a .verticali shaft,l all oscil-r` y.

lated'vertically 4by connected crank mechanism installed'within the base casting,"andv driven by `an electric-motor. The gang filing head is constructed with a series of vertically *positioned files, adjustably retainedy therein Vby vfixedly attached le holders, all of which oscillates with the gang filing head.V YSuit- V able holding mechanism is Inounted above the series of gang filesfor retainingthe work in a `lined rigid vposition forfengaging the files during their oscillatoryV movement.
